Abstract
The utility model relates to a direct black liquor filtering device for a papermaking spherical digester, which comprises a sphere and a direct black liquor filtering device arranged at the bottom of the sphere. A filter screen beading of the utility model is arranged on the surface of a filter screen, and a porous sieve plate is arranged below the filter screen, wherein, the porous sieve plate is supported on the inner wall of the sphere by a plurality of steel rods. The bottom of the sphere is provided with a black liquor outlet, and a connecting part of the black liquor outlet and the sphere is provided with a reinforcing plate. The utility model can direct filter black liquor, so that production technology is simplified. The extracting devices of the utility model is simple, the investment is less, and the improvement expenses of each spherical digester is no higher than 2500 rmb; the extraction rate of black liquor can reach 80 percents once, and the concentration of the black liquor can reach 13-14Be degrees, so that the utility model saves power and reduces running cost.
Description
The utility model relates to a kind of papermaking spherical digester and directly filters the black liquor device, is a kind of improvement to existing papermaking spherical digester.
Traditional paper production technology is that well-done paper pulp and black liquor are directly discharged by blow-off pipe simultaneously, operation such as washs after the cooling again and discharges black liquor.Because complex manufacturing causes extraction equipment complexity, investment is big, and operating cost height and extraction rate of black liquor are low, and the gained black liquid consistency is low, and consumption of power is big, makes back workshop section evaporation load strengthen.
The purpose of this utility model solves the existing in prior technology problem with regard to being, and a kind of papermaking spherical digester that provides directly filters the black liquor device.This device extraction equipment is simple, invests for a short time, and operating cost is low and production technology is simple, the extraction rate of black liquor height, and gained black liquid consistency height has been saved power greatly, has reduced the load of evaporation section.
Technical solution of the present utility model is to realize like this.Papermaking spherical digester directly filters the black liquor device, the direct filtration black liquor device that comprises spheroid and be located at the spheroid bottom, and this directly filters the black liquor device and is made up of filter screen beading, filter screen, porous sieve plate, rod iron, stiffening plate and black liquid outlet.The filter screen beading is located at the surface of filter screen, and filter screen is made by stainless steel material.The below of filter screen is a porous sieve plate, and porous sieve plate is supported on by several rod irons on the inwall of spheroid, and the bottom of spheroid is provided with black liquid outlet, and the junction of black liquid outlet and spheroid is provided with stiffening plate.
Described spheroid is a hollow body.
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is the utility model structural representation.
Among the figure: 1, filter screen beading 2, filter screen 3, porous sieve plate 4, rod iron 5, spheroid 6, stiffening plate 7, black liquid outlet
As shown in drawings, the utility model papermaking spherical digester directly filters the black liquor device, comprise spheroid 5 and directly filter the black liquor device, spheroid 5 is a hollow body, and its bottom is provided with the direct filtration black liquor device of being made up of filter screen beading 1, filter screen 2, porous sieve plate 3, rod iron 4, stiffening plate 6 and black liquid outlet 7.Filter screen beading 1 is located at the surface of filter screen 2, and filter screen 2 adopts stainless steel material to make.Porous sieve plate 3 is located at the below of filter screen 2, and by several rod irons 4 it is supported on the inwall of spheroid 5, and the bottom of spheroid 5 is provided with black liquid outlet 7, and black liquid outlet 7 is provided with stiffening plate 6 with the junction of spheroid 5.
During use, paper pulp black liquor under the steam pressure effect is extruded, and enters porous sieve plate 3 by the stainless steel filtering net 2 that is located at spheroid 5 bottoms, flows in the interlayer of porous sieve plate 3 and sphere shell through porous sieve plate 3, discharges from black liquid outlet 7 at last.
Compared with prior art, because the utility model can directly filter black liquor, greatly simplified production technology, Extraction equipment is simple, invest little, 2,500 yuan of every rotary spherical digester improvement expenses less thaies, extraction rate of black liquor once Can reach 80%, black liquid consistency can reach 13--14Be °, has not only greatly saved power and running cost Using remarkable reduction, is a kind of practical, has promotional value, and it is new to be applicable to that middle-size and small-size paper mill is used The type device.
